What are the chances?

So a friend of mine calls me and tells me he ran his prelude w/o oil. He wants to sell it. What are the chances of being able to fix the car? If I bought it would I have to replace the engine or overhaul it? please help!

This dude is a real lazy@ss when it comes to maintenance. He probably only changed the oil like twice the whole year he has owned it. The previous owner had just spent $2400 overhauling that engine! I'll see if I get a chance next week to look at it when I get off school for springbreak.
